What tests should be done for lung cancer? Three tests can detect lung cancer

Today we are introducing lung cancer. We all know that every disease should be examined accordingly, and these are very critical to the diagnosis and rehabilitation of the disease. So it is necessary for everyone to understand it carefully. So what examinations should be done for lung cancer?

1. Lung cancer examination: Finding cancer cells in sputum: Finding cancer cells in sputum is a convenient, fast, non-invasive examination that is easy to promote and apply. Once cancer cells are found in sputum, the diagnosis can be established, so it has diagnostic value. Lung cancer examination is particularly suitable for early diagnosis of lung cancer in the central part of the lung. The quality of sputum and the time of submission directly affect the detection rate of cancer cells. It is best to use the first sputum coughed up from the deep lungs after gargling in the morning and test it within 1 hour. Sputum containing blood is better, and purulent sputum should be avoided. Repeated submission can increase the positive rate.

2. Fiberoptic bronchoscopy: Lung cancer examination is particularly suitable for sputum positive for cancer cells, while chest CT is negative. In addition, the diagnosis rate of lesions near the hilum of the lung is relatively high. Fiberoptic bronchoscopy can be combined with fine needle puncture, X-ray-guided lung biopsy, etc. to further improve the positive rate.

3. Low-dose spiral CT examination of the chest: Lung cancer examination can detect tiny lesions that cannot be found by conventional chest X-rays. Some foreign studies suggest that the use of low-dose spiral CT to screen lung cancer can significantly improve the detection rate of early lung cancer. After surgical treatment of lung cancer, most patients can be cured and survive for a long time. Special attention should be paid to ground-glass lesions and small nodular lesions on CT, which may be more significant than in the past chest X-rays. New abnormal shadows on chest CT should be further examined or followed up to rule out the possibility of lung cancer.

The above contents are the examinations we want to introduce to you about lung cancer. I hope that after reading them, you will have a new understanding and knowledge of this disease. At the same time, I also hope that these can help more friends. Finally, I wish all friends to recover their health as soon as possible.
